1.logging operations used to use a technique called clear-cutting in which all of the trees in area are cut down what type of water pollution will this most likely lead to
A.toxic
B.sediment
C.nutrient
D.bacterial
Answer: B
2.when cars age or are poorly maintained they tend to leak oil onto roadways and parking lots this oil is washed into the nearest waterway with the next rainfall what type of water pollution does this cause
A.toxic
B.sediment
C.nutrient
D.bacterial
Answer: A
I agree with 1.
Answer: A
The water pollution caused by clear-cutting logging operations is most likely to lead to sediment pollution (Answer B). When all of the trees in an area are cut down, it removes the natural cover and root systems that help hold the soil in place. As a result, when it rains, the exposed soil can be washed away by runoff and end up in nearby waterways. This sediment runoff can cloud the water, block sunlight from reaching aquatic plants, and disrupt the habitat for fish and other aquatic organisms.
On the other hand, the water pollution caused by leaking oil from cars is toxic pollution (Answer A). When cars age or are poorly maintained, oil can leak onto roadways and parking lots. When it rains, this oil is washed into the nearest waterway, causing contamination. Oil is a toxic substance that can harm aquatic plants and animals. It can disrupt the balance of ecosystems, poison fish and other organisms, and degrade water quality. Therefore, the type of water pollution from leaking oil is toxic pollution.
